STATES DAVii) HENERSON HOUSTON,

retorno To (t/f wim/m 'i12/ty concern.'

Be it known that I, DAviD HENDERSON HOUSTON, a citizen ofthe United States, residing at Hunter, in the county of Cass and State of North Dakota, have invented certain new and useful Improvements in Folding Rolll'loldingPhotogra pliic Cameras; and l do hereby declare the following` to be a full, clear, and

yexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to folding' photographic cameras.

An object of my invention is to produce a very compact folding camera of substantial construction and having only one compartment for holding the rolls of sensitized film and exposing the lm to rays ot light passed through a lens.

Another object of my invention is to produce a camera having pivoted swinging brakes for producing tension upon the film, said brakes being` adapted to exclude light from the parts of the film extended between the rounded guides and the rolls ot' sensitized film.

My invention consists of novel features of construe-tion and combination of parts pointed out in the claims of this specication.

In the dra-wings similar characters of reference denote similar parts.

Figure l represents a front view of my cam era closed, showing the rear trame of the camerabellows fastened to the front part of the camera-easing. Fig. 3 represents a sectional plan view of my camera, showing the method of construction with one compartment. Fig. 3 represents a sectional plan view of my camera closed, having the film-rolls omitted and showing the spool and reel centering devices.

in fheinterior of my one-compartment folding camera there are no divisions, and the bellows is attached to the front side of the camera-casing and folds into the casing, together with the front of the cameraJ and the parts carried thereby. The casing is braced by angle-braces rigidly attached to the interior sides of the casing, and there are tilinedge guides extending between the rounded guides, and frction-brakes are pivoted to swing and bear upon the Wrapper of the rolls of sensitized AFilm and cause tension upon the ROLL-HOLDING PATENT EEICE.

film and also exclude light from the part of the film extended between the rounded guides and the rolls of sensitized film. The tensionbrakes may be pivoted upon the same pivots as the rounded guides, and a spring is positioned to bear upon the pivoted brakes, and the brake-springs may be advantageously placed upon the film-edge guides.

A indicates the camera-casing; B, the camera-front; C, the bellows; D, the rear frame ot the bellows; E, the film-edge guides; F, the rear side of the casing; G, the sight-aperture in the casing; il, the sensitized film and its wrapper; J, the fianges of the spools; K, the center of the supply-spool; L, the centerof the reel-spool; M, theangle-braces; N, the lens; P, the shutter for the lens; Q, the winding-key; R, the touch-button; Rl, the touch-button stein; S, the pivoted brake for the film; T, the rounded guides for the film; U, dotted lines indicating the marginal rays ot' light passing from the lens to the ends of the picture position in the camera; V, the folding supports 'for the front of the camera.

W points ont the corners of the anglebraees positioned to intercept the rays of light at the ray-lines U.

Y indicates the springs bearing upon the pivoted swinging brakes for the nlm-rolls; Z, the reel winding and centering device.

Z is one ot the snpply-spool-centering devices.

Having described my invention, i claiml. ln a photographic camera the combination of an oblong-shaped one-compartment casing for holding the spools of sensitized film and exposing the film to rays of light passed through a lens, spool-centering devices in one end of said casing, reel-centering devices in the opposite end of the casing, rounded guides for the sensitized film, said rrounded guides positioned near the rear interior side of the easing, a bellows having its rear end connected at the front side of the casing, afront and lens and shutter closing the front end of said bellows, the front side of the cameracasing having ray-intercepting projections positioned at the right and left ends of the front aperture of the eameraeasing, said rayintercepting projections positioned in line between the rays oi light passing the lens when in use and the said rounded guides positioned near the rear interior side of the casing, said front of the bellows and the parts carried ythereby and the bellows all adapted to fold tion of an oblong-shaped one-compartmentv casing for holding the spools of sensitized film and exposing the film to rays of light passed through a lens, spool-centering devices in one end of said casing, reel-centering devices in the opposite end of the casing, rounded guides for the sensitized film, said rounded guides positioned near thefrear interior side of the casing, film-edge guides positioned at opposite interior sides of the casing and in line between the said rounded guides, a bellows having its rear end connected at the front side of the casing, a front and lens and shutter closing the frontend of said bellows, said front of the bellows and the vparts carried .thereby and thev bellows al1 adapted to fold into the central portion ot' the said one-compartment casing and be carried in the central space between the supply and reel spools, and means for extending the bellows and supporting the front of 'said bellows in a position where the lens carried in said front will be vfocused upon the sensitized lrn when the said film is extended across the rear interior part of the said one-compartment casing.

3. In a photographic camera the combina.

tion of an oblong-shaped one-compartment lcasing for holding the spools of sensitized film and exposing the film to rays of light passed through a lens,spoolcenteriug devices in one end of the casing, reel-centering devices in the opposite end of the casing, rounded guides for the sensitized film, said rounded guides positioned near the rear interior side of the casing, a bellows having its rear endconnected to a support-frame, said support -frame having angle-arms rigidly united to the inner edge sides 'of the cameracasing, a frontfand lens and shutter closing the front end of said bellows, said front of the bellows and the parts carried thereby and the bellows all adapted to fold into the central portion of the said one-compartment casing and be carried in the central space between th'e supply and reel spools, and means for extending the bellows and supporting the front of the said bellows in a position where the lens carried in said front will loe focused upon the sensitized lm when the said film is extended across the rear interior part of the said one-compartment camera.

p 4. In a photographic camera the combination of a one-compartment casing for holding the spools of sensitized film and exposing the film to rays of light passed through a lens, spool and reel centering devices in the casing, rounded guidesfor the sensitized film, lightexcluding friction brakes pivoted at the rounded guides, said light-excluding frictionbrakes adapted to intercept light and thereby shield the parts of the sensitized lm extended between the rounded guides and the rolls of film.

5. In a photographic camera the combination of a one-compartment casing for holding the spools of sensitized film and exposing the film to rays of light passed through a lens,

-spool and reel centering devices in the casing,

rounded guides for the sensitized film, ilmedge guides at opposite sides of the casing, springs supported upon the said film-edge guides, said springs positioned to bear upon light-excluding friction-brakes, said light-excluding friction-brakes pivoted to swing and extend from the said rounded guides 'to the roll of sensitized iilrn.

In testimony whereof I affix my signature in presence of two witnesses.
